  • Suppression Mechanisms of Alkali Metal Compounds
    SUPPRESSION MECHANISMS OF ALKALI METAL COMPOUNDS Bradley A. Williams and James W. Fleming Chemistry Division, Code 61x5 US Naval Research Lnhoratory Washington, DC 20375-5342, USA INTRODUCTION Alkali metal compounds, particularly those of sodium and potassium, are widely used as fire suppressants. Of particular note is that small NuHCOi particles have been found to be 2-4 times more effective by mass than Halon 1301 in extinguishing both eountertlow flames [ I] and cup- burner flames [?]. Furthermore, studies in our laboratory have found that potassium bicarbonate is some 2.5 times more efficient by weight at suppression than sodium bicarhonatc. The primary limitation associated with the use of alkali metal compounds is dispersal. since all known compounds have very low volatility and must he delivered to the fire either as powders or in (usually aqueous) solution. Although powders based on alkali metals have been used for many years, their mode of effective- ness has not generally been agreed upon. Thermal effects [3],namely, the vaporization of the particles as well as radiative energy transfer out of the flame. and both homogeneous (gas phase) and heterogeneous (surface) chemistry have been postulated as mechanisms by which alkali metals suppress fires [4]. Complicating these issues is the fact that for powders, particle size and morphology have been found to affect the suppression properties significantly [I]. In addition to sodium and potassium, other alkali metals have been studied, albeit to a consider- ably lesser extent. The general finding is that the suppression effectiveness increases with atomic weight: potassium is more effective than sodium, which is in turn more effective than lithium [4].

  • High Potassium Eating 
    High Potassium Eating Why is eating a high potassium diet important? Potassium is a mineral found naturally in many foods. It can help lower blood pressure and may lower the risk of heart disease and stroke. It is used in your body to make the heart beat, to build protein and muscle, to make energy from food and to help kidneys work. Potassium-rich foods maintain your body’s potassium levels. Depending on your age, aim for a daily intake of: Age group (years) Recommended Potassium Intake (mg/day) 1-3 3000 4-8 3800 9-13 4500 14-70 4700 >70 4700 Pregnancy (all age groups) 4700 Breastfeeding (all age groups) 5100 Your Doctor will closely watch the potassium level in your blood. He will tell you if you need to eat more or less high potassium foods. You may need more potassium if you: take certain medications such as some types of diuretics (water pills). are losing too much potassium through urine, sweat or diarrhea. have high blood pressure.

  • Potassium Content of Foods
    Potassium Content of Foods This is a guide to help you as you watch the amount of potassium you eat each day. The general guideline is to limit your intake of high potassium foods, and to choose acceptable potassium foods more often instead. Your provider may have a goal daily maximum of potassium intake per day, which is noted here: ____________ milligrams (mg) potassium per day. Serving sizes of food are important. If you eat more than 1 serving size of foods that are low or moderate in potassium, you can end up consuming a total higher amount of potassium. Actual values may vary depending on the product or processing. You can also refer to food labels or other resources for actual values.

  • Periodic Table Key Concepts
    Periodic Table Key Concepts Periodic Table Basics The periodic table is a table of all the elements which make up matter Elements initially grouped in a table by Dmitri Mendeleev Symbols – each element has a symbol which is either a Capital Letter or a Capital Letter followed by a lower case letter Atomic Number – the number above an element’s symbol which shows the number of protons Atomic Mass – the number found below an elements symbol which shows the mass of the element. Mass = the number of protons + the number of neutrons Metals – the elements which have the properties of malleability, luster, and conductivity o These elements are good conductors of electricity & heat. o Found to the left of the zig-zag line on the periodic table Nonmetals – do not have the properties of metals. Found to the right of the zig-zag line Metalloids – elements found along the zig-zag line of the periodic table and have some properties of metals and nonmetals (B, Si, Ge, As, Sb, Te, and Po) Groups The columns going up and down (There are 18 groups) Group 1: Hydrogen, Lithium, Sodium, Potassium, Rubidium, Cesium, and Francium Elements arranged so that elements with similar properties would be in the same group. o Group 1 Alkali Metals - highly reactive metals o Group 2 Alkali Earth Metals – reactive metals o Group 3-12 Transition Metals o Group 17 Halogens – highly reactive non-metals o Group 18 Noble Gases - do not react or combine with any other elements. Elements are grouped according to their properties or reactivity Reactivity is determined by the number of electrons in an element’s outer energy level These electrons are called valence electrons Periods The rows that run from left to right on the periodic table (There are 7 periods) Period 1 contains 2 elements, Hydrogen and Helium.
